What do you do when you're 25 and you've just inked a new contract for 12-years, $325 million dollars? Well, if you're Miami Marlins slugger Giancarlo Stanton, you hit the South Beach club scene, of course.

TMZ Sports obtained photos of Stanton and his entourage partying inside a popular club known as the FDR at the Delano Hotel. Stanton was photographed making merriment until the early AM, with friends and a host of attractive young women.

Stanton also was reportedly gifted a $20,000 bottle of champagne but a Miami socialite by the name Julz. Known as "Moët Nectar Impérial Rosé Leopard Luxury Edition Methuselah," the six-liter bottle was one of only 60 bottles of its ilk ever created, and it came covered in 22-carat gold leaf.

Afterwards, Julz posted a photo of the festivities to her Instagram account. Therein, she was effusive with praise for Stanton, telling her followers: "Last night at @fdratdelano was just way too crazy !! #FDRmondays are awesome I am so proud of what this party has become! BUT I am even more proud of this guy @giancarlo818!!! He is so humble, well mannered and motivated...It's great to see good people receive such incredible blessings."
